It’s a UI (client-side) function action called ‘function’ which has a method called:
It can take a tilde delimited list (such as those returned from mutli-searchResult and convert it into a SQL list campatible for WHERE IN() clause
Follow this link to see how to set it up. Basically the textbox or SearchChipComponent sets TransView.Parts then an event TransView.PArtsOnChanged execs the ui function to convert ‘partnum1~partnum2’ to ‘partnum1’,‘partnum2’ and sets then in TransView.PartsSQL which is the field your grid WHERE is filtering using.
tick the KeyField box on the textbox component. This makes it editable before rows exist in the bound dataview (that’s all it does, AFAIK)
PS - if you like the multi-search aspects of this, use a SearchChipComponent instead of textbox. As shown here.
